From Xinxiang Ceramic Mug Manufacturer,The safety of cups has become a hot topic in recent years. According to experts, most of the cups, whether plastic, ceramic or metal, are safe. However, if the characteristics of various cups are ignored in the application, the toxicity of cups may endanger health.
1. Plastic cups are most afraid of high temperature.
Not long ago, there were reports in the United States that plastic kettles had potential health hazards, which aroused people's doubts about the safety of plastic products. Food safety experts say plastic cups are best not colored. Many plastic cups have beautiful color patterns on the surface. If the contents of lead, cadmium and other metal elements in the patterns exceed the standard, they will cause harm to the human body. There is a maintenance film on the surface of ordinary plastic products. Once the film is cut by hard ware, harmful substances will be released. The surface of inferior plastic cups is often not lubricated and harmful substances can easily leak out.
Consumers should try their best to choose plastic cups without decorative patterns, colorless and tasteless, bright appearance and strong handle. Because coloring must take part in some additives, the safety of products will be reduced. For example, if you put oil, vinegar, beverage in a colored plastic bottle, you will dissolve a part of the color masterbatch, which will be harmful to your health.
At present, most of the plastic cups sold on the market are polyethylene and polypropylene products, both of which can withstand high temperatures of more than 100 degrees Celsius and are comparatively safe to use. Consumers should pay attention to whether the words PE (polyethylene) and P P (polypropylene) can be labeled on the goods when choosing.
In addition, pay attention to temperature when using plastic products. Usually plastic products have a temperature-resistant range, even at about 110 degrees Celsius. For example, environmentally friendly fast food boxes can be safely used as long as the temperature does not exceed 120-130 degrees Celsius; rigid plastic cups, boxes, etc., the temperature range of qualified products can be as high as 160 degrees Celsius, even with microwave oven hot rice, hot milk will not produce toxicity.
2. Boiling-detoxification of ceramic mugs
Ceramic mugs are one of the most commonly used cups in most families, but the glaze on the surface of ceramics may become a killer of health. Lead, mercury, radium and cadmium are harmful elements in the glaze. Radioactive elements radium can kill white blood cells. Cadmium and lead can cause liver or other visceral poisoning. Mercury can cause liver and kidney cirrhosis. When using unqualified ceramic products, these harmful substances will dissolve. As food enters the human body, chronic poisoning will occur over a long period of time.
Ceramic cups must be purchased in the right market, and inferior products must not be purchased cheaply. When purchasing, pay attention to the color of the cup. Touch the outside of the cup with your hand to see if the inner wall is bright. At the same time, use your nose to smell if it smells bad. Boil the cup in boiling water for 5 minutes before use, or soak it in vinegar for 2-3 minutes to dissolve the toxic substances in the cup.
3. Anti-acid and alkali corrosion of stainless steel cups
Although stainless steel is more resistant to corrosion than other metals, if improperly used, trace metal elements in stainless steel will also accumulate gradually in the human body, reaching a certain amount will endanger human health, such as nickel is a carcinogen. Therefore, when using stainless steel cups, special care should be taken not to store strong acid or alkaline food for a long time to avoid the dissolution of metal elements such as chromium and nickel. Stainless steel utensils should not be used to boil Chinese medicines in order to prevent stainless steel from reacting with alkaloids and organic acids in Chinese medicines under heating conditions to produce more toxic chemicals. At the same time, it should be noted that stainless steel cups should not be washed with strong alkali and strong oxidizing agents; if stainless steel cups are found to be deformed or damaged, they should be replaced in time.
Experts also warn against using aluminium cups as much as possible, because too much aluminium accumulates in the body can cause intellectual decline. Aluminum cups can't be used with iron cups. Chemicals can cause more aluminium ions to enter the food.
